What is claimed is: 
     
       1. A compound whose structure is: ##STR18## wherein: R 1  is a radical selected from the group consisting of phenyl, lower alkyl and cycloalkyl radicals, each said radical having a lower alkyl quaternary di- or tri-alkylammonium substituent; and R 2  with R 3  is a benzisothiazole ring system.   
     
     
       2. The compound according to claim 1 wherein the alkylammonium substituted radical is a 3-trimethylammoniomethyl radical.
